I have one channel that never records audio in MythTV. I record the same half hour show on other channels. The ones that do record on other channels are usually about 3.5GB, the ones on this bad channel are 2.9GB, so I am assuming that the card isnt picking up any audio to record. I have a friend with OTA hooked directly up to his TV, and he gets audio on this channel just fine. Even LiveTV has no audio on my system. If I play the recorded files in VLC, they show an audio track, but it says 0 packets decoded, 0 played back. Is this something like having to set a PID on my system somewhere? Or could it be a problem in tuning? I forgot to mention my signal levels are right around 85% for this channel, and the video portion looks great.
